Abstract
Abstract A test circuit arrangement for testing computer-controlled communications switching systems each having a central network and a central processor unit, as well as subscriber sets and/or line sets connectable to the network for analog and/or digital information transmission. These subscriber sets and/or line sets are in communication with the central processor unit under the control of a group processor unit adapted to the plurality of subscriber sets and/or line sets. A communications switching system to be tested is connected to a line trunk group configuration composed of subscriber and line sets, manual switching position and digital stations and is function-tested with a personal computer unit connectable via the group processor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A test circuit arrangement for testing computer-controlled communications switching systems each respectively having a central network and a central processor unit, as well as having a plurality of subscriber sets and/or line sets connectable to the network for analog and/or digital information transmission that, in combination with the central processor unit, are respectively under the control of a group processor unit adapted to the plurality of subscriber sets and/or line sets, comprising: a line trunk group configuration of the computer-controlled communications switching system, the line trunk group configuration being allocated to a single group processor unit and being formed of subscriber sets and/or line sets; the group processor unit connected to a personal computer unit via an interface unit (HDLC); the personal computer unit connected via a first operating interface unit to the central processor unit that controls an operating system of the communication switching system; and a manual switching position device and a digital station each of which is controllable by the group processor unit via a digital set and each of which being directly connected t the communications switching system to be tested.
